I was wondering if there has been an investigation about a missing passenger on the CTMA Vacancier in September 2016?

An american man was reported missing by relatives to the crew while the ship was between Havre-Saint-Pierre and Quebec City. There were conflicting reports if the man stayed aboard the ship while in Havre-Saint-Pierre or went to shore. The question was if he failed to return to the ship or went overboard after the departure.
